The AtAHAS polypeptide is in light blue. FAD, ThAThDP, and BS are in yellow, light brown, and green carbon atoms, respectively. The black thin lines represent BS in the WT AtAHAS-BS structure that has been superimposed to the P197T-BS structure. Electron densities (2Fo-Fc map) in gray correspond to BS contoured at 1.2 σ. The interaction representations are as in Fig. 7. Grey dashed cylinders represent π–π interactions. Yellow dashed cylinders represent sulfur–π interactions. Blue dashed cylinders represent hydrophobic interactions. Dashed lines represent hydrogen bonds (black).
